Title: Pin fin type heat exchanger
Inventor: OSAWA TORU
IPC: F28F17/00
Filed: 1989-10-24
Abstract: PURPOSE:To prevent builtup of water droplets, an increase in a ventilation resistance and a decrease in heat exchanging efficiency by horizontally disposing pin fins in a longitudinal axis direction in a heat exchanger in which the fins are disposed between fluid pipes in tubes. CONSTITUTION:A plurality of pin fins 2 are horizontally disposed in parallel at a predetermined interval between fluids in tubes adjacent to fluid pipes 1, and respectively secured to the flat parts of the pipes 1. When refrigerant such as fluorocarbon, etc., compressed by a compressor is used as the fluid in the tube, oil in the compressor tends to be built up in a U-shaped bend of a lower position of U-shaped bends at both ends in a serpentine type. Accordingly, when an angle formed between a plane including all center lines of the longitudinal directions of the fluid pipes of linear tubes and a vertical direction is theta(0 deg.<=theta<=90 deg.), it is desired to set theta>=45 deg. or theta>=180 deg. to prevent oil from storing in the pipe. It can also prevent the oil from building up irrespective of the thetaby forming a header structure.

Title: Valve controller driven by electromagnetic force
Inventor: KAWAMURA HIDEO
IPC: F01L9/20
Filed: 1988-10-31
Abstract: PURPOSE:To improve the volume efficiency in all the region by increasing the opening/closing speed of an intake/exhaust valve of the crank angle, accompanied with the increase of the engine revolution speed. CONSTITUTION:A suction valve 8 is always pulled upwardly, since a permanent magnet 52 attracts an upper magnetic body 57. When a drive signal is outputted from a control unit 56 to an electromagnet 53, a magnetic path is formed through a lower magnetic body 58, and the electromagnet 53 attracts the lower magnetic body 58 downward. Then, the revolution speed of an engine 54 which is detected by a revolution speed sensor 55 is once memorized in a RAM 56e. The valve opening degree is determined from a relative table between the engine revolution speed memorized in a ROM 56d and the valve opening degree and the engine revolution speed memorized in the RAM 56e. Therefore, the valve is opened and closed at the higher speed for a crank angle in the high speed revolution, while in the low speed revolution, the valve is opened and closed at the lower speed. Therefore, the volume efficiency of the intake/exhaust gas can be improved in all the engine revolution speed range.

A second time limiting device 40 is connected to both ends of a relay contact point 52 and performs a periodical defrosting operation under a different period differing from that of the first time limiting device 44. Since the time limiting device 40 is connected in parallel by a synchronizing circuit 50 in respect to a series-connected circuit 47 arranged in each of freezing devices 10, a defrosting operation starting time of each of cooling devices R is determined by the time limiting devices 44 and 40. A defrosting by both time limiting devices 44 and 40, a defrosting with only the time limiting device 40 and a defrosting only with the time limiting device 44 can be selected in response to an opening or closing state of an opening or closing device 45 of the series-connected circuit 47 and a fixing state of the time limiting device 40 and then a simultaneous or concurrent defrosting of the freezing devices through a synchronous circuit 50 can be carried out.

Title: Protection circuit using counter
Inventor: SHINOHARA AKIO
IPC: H04M3/06
Filed: 1990-10-15
Abstract: PURPOSE:To realize the inexpensive protection circuit whose circuit scale is small by implementing protection through a count-up or reset of an n-adic count means. CONSTITUTION:An error input signal passing through a selection means 10 is used for a count-up and reset signal to an n-adic count means 20, which is counted up or reset by using a pulse generated from a pulse generating means 40. An output of an inverting means 30 is inverted by a carry output outputted from the count means 20 when count-up consecutively takes place for n-times to detect and release output of the error input signal. Since the protection is implemented by the count-up and reset of the n-adic count means 20, the protection circuit is configurated inexpensively with a small circuit scale.

The beams are then introduced to a detector 10 where the beams are converted to electric signals. The converted reference light quantity R and sample light quantity S are amplified by an amplifier 11 and are inputted as the digital quantities DR, DS proportional to the respective light quantities by an A/D converter 12 to a computer 13. While the magnitude of the digital quantities DR, DS is monitored by the computer 13 in such a manner that the light quantities S, R enter the optimum range of the converter 12, the size of the aperture of the variable diaphragm 3 is changed. The measurement is made by maintaining the respective conditions of the spectroscope 2, the detector 10 and the amplifier 11 under the specified conditions during the measurement and maintaining the specified purity of the wavelength in this way.

Title: Production of surface-treated silica
Inventor: MATSUMURA KAZUYUKI
IPC: C09C1/30
Filed: 1993-11-05
Abstract: PURPOSE:To produce a surface-treated silica excellent in uniformity, stability, processibility, and safety by reacting a specific organosilicon compd. with silica dispersed in water or a water-contg. org. solvent in the presence of a specific catalyst. CONSTITUTION:The surface-treated silica is produced by reacting 0.001-10 pts.wt. organosilicon compd. having an alkoxy group directly bonded to a silicon atom with 100 pts.wt. silica dispersed in water or a water-contg. org. solvent in the presence of an org. or inorg. fluorine-contg. silicon compd. or salt having an SiF bond as the catalyst. An amt. of the organosilicon compd. reacted lower than 0.001 pt.wt. results in an insufficiently surface-treated silica; an amt. higher than 10 pts.wt. much increases the cost without increasing the effect so much.
